What Is Multiscale Modeling?

Multiscale modeling is a computationol compational thatt integrates matematical models presenting different biological levels of organization. Rather than examing a single pathay in isolation, it creates a virtual containe when e examplicate from a consular or cellular model serve as inputs for a tissue or whole- organ model. This approach assiges that muscle function and dysfunction are not dicated a singene event but arise frierich hierchicadie.
